"The Great Divide Mountain Bike Route (GDMBR) is a continuous long distance cycling route from Banff, Alberta, Canada to Antelope Wells, New Mexico, USA. As of 2010, the route is 2745 miles (4417 KM) long; its length is likely to change over time as the GDMBR is continually being refined to improve it. The GDMBR was developed by the Adventure Cycling Association (ACA) and was inaugurated in 1998.[1] A set of highly detailed route maps is available from the ACA. A guidebook has also been published."
